Science develops best when its concepts and conclusions are integrated into the broader human culture and its concerns for ultimate meaning and value. Scientists cannot, therefore, hold themselves entirely aloof from the sorts of issues dealt with by philosophers and theologians. By devoting to these issues something of the energy and care they give to their research in science, they can help others realize more fully the human potentialities of their discoveries. They can also come to appreciate for themselves that these discoveries cannot be a genuine substitute for knowledge of the truly ultimate. Science can purify religion from error and superstition; religion can purify science from idolatry and false absolutes. Each can draw the other into a wider world, a world in which both can flourish.

This inscription awakens the memory of people whose sons and daughters were destined for total extermination. This people draws its origin from Abraham, our Father in faith. The very people that received from God the commandment, thou shalt not kill, itself experienced in a special measure what is meant by killing. It is not permissible for anyone to pass by this inscription with indifference.

When you wonder about the mystery of yourself, look to Christ who gives you the meaning of life. When you wonder what it means to be a mature person, look to Christ who is the fullness of humanity. And when you wonder about your role in the future of the world and of the United States, look to Christ.

We are now standing in the face of the greatest historical confrontation humanity has ever experienced. I do not think the wide circle of the American Society, or the wide circle of the Christian Community realise this fully. We are now facing the final confrontation between the Church and the antichurch, between the Gospel and the antigospel, between Christ and the antichrist. This confrontation lies within the plans of Divine Providence. It is, therefore, in God's Plan, and it must be a trial which the Church must take up, and face courageously.

All human activity takes place within a culture and interacts with culture. For an adequate formation of a culture, the involvement of the whole man is required, whereby he exercises his creativity, intelligence, and knowledge of the world and of people. Furthermore, he displays his capacity for self-control, personal sacrifice, solidarity and readiness to promote the common good.

Faced with problems and disappointments, many people will try to escape from their responsibility: escape in selfishness, escape in sexual pleasure, escape in drugs, escape in violence, escape in indifference and cynical attitudes. But today, I propose to you the option of love, which is the opposite of escape.

Christians and Muslims, we have many things in common, as believers and as human beings. We live in the same world, marked by many signs of hope, but also by multiple signs of anguish. For us, Abraham is a very model of faith in God, of submission to his will and of confidence in his goodness. We believe in the same God, the one God, the living God, the God who created the world and brings his creatures to their perfection.

Not all are called to be artists in the specific sense of the term. Yet, as Genesis has it, all men and women are entrusted with the task of crafting their own life: in a certain sense, they are to make of it a work of art, a masterpiece.

Man is called to a fullness of life which far exceeds the dimensions of his earthly existence, because it consists in sharing the very life of God. The loftiness of this supernatural vocation reveals the greatness and the inestimable value of human life even in its temporal phase.
